Case Reports
Accidental hypoglycaemia caused by an arterial flush drug error: a case report and contributory causes analysis.
In 2008, the National Patient Safety Agency (NPSA) issued a Rapid Response Report concerning problems with infusions and sampling from arterial lines. The risk of blood sample contamination from glucose-containing arterial line infusions was highlighted and changes in arterial line management were recommended. Despite this guidance, errors with arterial line infusions remain common. ⋯ This case occurred despite the implementation of the practice changes recommended in the 2008 NPSA alert. We report an analysis of the factors contributing to this incident using the Yorkshire Contributory Factors Framework. We discuss the nature of the errors that occurred and list the consequent changes in practice implemented on our unit to prevent recurrence of this incident, which go well beyond those recommended by the NPSA in 2008.

Intensive care capacity planning based on factual or forecasted mean admission numbers and mean length of stay without taking non-linearity and variability into account is fraught with error. Simulation modelling may allow for a more accurate assessment of capacity needs. We developed a generic intensive care simulation model using data generated from anonymised patient records of all admissions to four different hospital intensive care units. ⋯ The most important characteristic of the final model was the dependency of admission rate on actual occupancy. Occupancy, coverage and transfers of the final model were found to be within 2% of the actual data for all four simulated intensive care units. We have shown that this model could provide accurate decision support for planning critical care resource requirements.
